Azure Blockchain Workbench now available as Public Preview!

Hey folks,   Excited to share that this morning at Build we announced the release of Azure Blockchain Workbench (formerly App Builder)! Workbench is the fastest way to get started with blockchain...

Hi,

 

four (related) questions. Deploying Workbench includes the creation of a (currently ethereum) blockchain.

  • Is it possible to use another (ethereum) blockchain instance?
  • Is it possible to add nodes to the generated blockchain instance?
  • Is it possible to access the blockchaim via the standard RPC API?
  •  In the docu there is a hint, that Proof of Authority is used, is this correct?

Thanks,

Christoph

    Thanks for the great questions. Here are the answers to your questions:

    • Is it possible to use another (ethereum) blockchain instance?
      • Not yet, although this work is in our backlog
    • Is it possible to add nodes to the generated blockchain instance?
      • Not via our API or UI at this time
    • Is it possible to access the blockchaim via the standard RPC API?
      • No, we turned off access to the RPC API for security. You can open access via the portal by modifying the network security group rules
    •  In the docu there is a hint, that Proof of Authority is used, is this correct?
      • Yes, we are using Ethereum PoA

      Hi Zeyad,

       

      thanks for the fast answer! So as I understand it, for now it is great for PoCs. But using it in production  is still some time away, correct?

       

      Best

      Christoph

        We are working on hardening Workbench so it can be used for production. We would love to hear from customers on requirements for making Workbench ready for your production solutions. Feel free to post here or on user Voice:

      Can you please outline how exactly to do this? Also I would add this to your documentation. This is all great but much more valuable if you can actually access the blockchain. Thanks it looks really interesting!

        Good recommendation on the article. In the meanwhile, go to your resource group with the deployed Workbench. Select the network security group resource (note there are two, one is for the worker, which represents Workbench microservices). Modify the appropriate inbound security rules to allow access.
